Thank you very much for your help I realized that there's much better idea than my first idea.... I can plug all my drives the sata plug are not a problem :-) I use around 4.5TB on my current raid 5 I will continue to think on this problem and in the meanwhile try to find another disk i didn't think about : > > In general an in-place migration is a very dangerous operation > > because it stresses existing hardware a lot plus it uses code > > that is rarely used and is quite complex.

The > alternatives imho are worse ... at first i thought about using rsync to do my copy (anyway i don't have a GUI) at second i thought that an in-place migration would be a nice and safe operation now i don't what to think ? the 3 4TB disk are new but the 2 2TB are 4 year old and consumer grade (the 4TB are seagate NAS HDD) so i'm asking myself should I do a copy (with rsync or another tool) or an in-place migration ? which one is the safest ? thanks again Cheers, Math -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
